Question

Ben has a 40% chance of being selected as the president of the school sports club and a 70% chance of being elected editor of the school magazine.

What is the probability that Ben will be selected as the president of the sports club and will also be elected editor of the school magazine?

A) 0.3%
B) 1.1%
C) 14%
D)28%

Answer 1

70 / 40 = 1.75
(not even close)

So it's 70/ 40 % = 28
It's D

When you calculated this, did you add a percent %?

Answer 2

no

Answer 3

oh, well next time just make sure add the percent :)

Answer 4

how does that process get us to 28% ?

Answer 5

so you would take the 70 and divide it by 40

Answer 6

wait no I still don't get it

Answer 7

70 / 40 % = 28.

Try it with your calculator :)

Answer 8

theres a rule:

P(A n B) = P(A) * P(B) if A and B are independant

Answer 9

oh 40% so I would divide 70 by 0.4

Answer 10

Maliboo is not making any sense to me ....

Answer 11

still don't get it

Answer 12

heres the rule, again:

P(A n B) = P(A) * P(B) if A and B are independant

good luck with it

Answer 13

Guys, if you have a calculator
please do 70 divided by 40 %,
BUT YOU MUST MAKE SURE YOU ADD THE PERCENT AFTER 40
or it won't be 28

Answer 14

so would 70 and 40 be A n B

Answer 15

.70 and .40 yes

Answer 16

When I did 70/40% I got 175

Answer 17

dont follow the advice of a fool ...

Answer 18

What is P then

Answer 19

P(A) means: the probability of event A

Answer 20

what class are you working this in?

Answer 21

math

Answer 22

math is a broad subject. you should have been exposed to some of this notation during the class at least

Answer 23

define our events, what are we looking for?

Answer 24

if I do 0.40 * 0.70 I get 0.28 so @Maliboo was correct

Answer 25

her answer was right, her process was garbage

Answer 26

hey thats not very nice to say there could be multiple methods

Answer 27

Well, when I did it on MY CALCULATOR I got 28.

Answer 28

no, there arent multiple ways of processing this.

70/40 is not .28 no matter what buttons you push on a calculator

Answer 29

I unfanned you amistre64

Answer 30

the next type of question you get like this .. you want to work the correct process, not take some strangers willy nilly nonsense that they cant even perform.

Answer 31

good luck then, its your grade ....

Answer 32

THANK YOU @Maliboo

Answer 33

Your welcome :)

Answer 34

spose someone process was:

i took the retrograde of mars with jupiters orbital apex, and got .28

gets .28 but the rest is not in any way a reasonable assessment of the information. just saying :)
