PLEASE HELP!!! 1. sporting goods store recieved an order of 64 baseball caps, of which 16 were green. if 1 of 64 caps is selected at random what is the probability it will not green? A. 25% B. 75% C. 80% D. 50% 2. lynn and Dawn tossed a coin 70 times and got heads 44 times. what is the experimental probability of tossing heads using lynn and dawn's results? A. 35/22 B. 13/35 C. 25/13 D. 22/35
probability of an event = number of favorable cases / total number of cases
so for the first question here number of favorable cases = number of green caps = 16 total number of cases = total number of caps = 64
so it would be 16/64 ?
whcih would equal to 25% correct?
correct
you can apply the same formula for the second question try it and tell me what you get to check it for you
what is the formla for the second one im really confused :P
\[\frac{ Favorable outcome }{ Overall number of outcomes }\]
same formula number of favorable cases = number of head outcomes = 44 total number of cases = total number tosses = 70
Simplify \(\ 44/70 \)
44/70 =0.625= 31/50
is that right :P
Um o.0 they both have a common multiple of 2 >.>
2 is the common divisor* @tHe_FiZiCx99 lol
im still confused cause the answer i got isnt in the answer choices :P
I always mix those terms up X_X i understand it though, i'm kinda bad at explaining ;-;
44/2 = ?
so @rockstargirl17 you need to divide both the numerator and the denominator of 44/70 by the GCD which is 2 here to get the simplified form
oh okay so it would be 22/35
@tHe_FiZiCx99 lol i used to mix too :P
Yesh
yeah @rockstargirl17 that's right
thank you :) could you help me with another one cause im confused on this one too
I always mix up factors and multiples ._.
post the question @rockstargirl17 and i'll try to help
it's better that you post it as a new question though.
A garden store has the following miscellaneous flower bulbs in a basket: 5 amaryllis 6 daffoldils 4 lilies 3 tulips A customer bought 4 bulbs from the basket one of each type of flower. if the next customer selets 1 of the remaining bulbs at random, which is closest to the probability that customer will get a daffodil bulb? A. 36% B. 27% C. 29% D. 21%
after the first customer bought one of each type how many flowers of each type will be left ?
4 amaryllis 5 daffodils 3 lilies 2 tulips right?
ok, what is the total number of flowers then ?
If he bought 4 flowers, one of each type then subtract 1 from each, then add them up. He wants a daffodils so the probability if him getting one is 5/14
it would be 14
great so number of daffodils is 5 total number of flowers is 14 so what is the probability that customer will get a daffodil ?
._.
36% correct?
yep
Yes, completely ignored my explanation ;-;
lol @tHe_FiZiCx99 she wants to learn how she can do it by herself not just getting the answer, so it would be better to guide her through rather than giving the answer
you explained it well though
._. I did explain >.>
yeah told you you explained very well, but just guiding can be better some times good job though :)
