Question

HELP PLEASE!!!

1.) True or False: "The sum of all the probabilities of outcomes of an event is equal to 100.

2.) If I roll a fair die 100 times, about how many times would I roll a 4?
A.) 25 times
B.) 67 times
C.) 17 times
D.) There is not enough information to answer.

Answer 1

1. false

2. 17 times

Explanation:

The sum of all the probabilities of outcomes of an event is equal to 1

2. A die has 1,2,3,4,5,6

P(4) = number of 4's/ total numbers

= 1/6

Multiply the number of roll's by the probability of getting a 4

100 *1/6 = 50/3 = 16 2/3

This is approximately 17
