favorable outcomes= 12

Answer 7

b?

Answer 8

no

Answer 9

let's think about it

Answer 10

the denominator of you probability would be 33 since there are 33 people in all

Answer 11

no, I'm sorry
the definition is:
probability= favorable outcomes/ possible outcomes

Answer 12

ok

Answer 13

d?

Answer 14

Answer 22

yes, C is correct

Answer 23

yay!

Answer 24

yes! it is option C

Answer 25

The probability that an event will occur is 100%. Which of these best describes the likelihood of the event occurring?

Likely
Certain
Unlikely
Impossible

Answer 26

total boys = 12
total girls=21
total children =12+21 =33
probability(a boy name is drawn) =total number of favourable events/total no. of events P=12/33 :)

Answer 27

well, if it 100%, then it would be certain

Answer 28

100% is the maximum value for a probability

Answer 36

@Michele_Laino

Answer 37

sure event has probability = 1
likely event has probability>=0.5
unliky event has probability<0.5
impossible events have probability=0

so which one is the event given in the question ??

Answer 38

um, unlikely?

Answer 39

and 2/3 is greater than 0.5

Answer 40

2/3=??

Answer 41

Answer 48

)A spinner is divided into sections of equal size, of which some are red, some are blue, and the remaining are green. The probability of the arrow landing on a section colored red is 50%. The probability of the arrow landing on a section colored blue is 10%. What is the probability of the arrow landing on a section colored green?

10%
40%
50%
60%

Answer 49

the sum of all probabilities has to be equal to 100%

Answer 50

ok

Answer 51

40%?

Answer 52

yes!

Answer 53

yay!

Answer 54

Answer 60

A bag contains 50 marbles, 10 of which are blue, 8 are red, 20 are green, and 12 are purple. Marcie takes a marble out of the bag, records the color, and returns it to the bag. How many red marbles should she expect after 500 trials?

80
100
120
200

Answer 61

120?

Answer 62

@Michele_Laino

Answer 63

the probability to get a red marble is 8/50

Answer 64

so the favorable outcomes are, probability times possible outcomes:
\[\Large \frac{8}{{50}} \cdot 500 = ...?\]
