Question

Sherri rolls a dice, numbered 1 to 6, 64 times. How many times can she expect to roll an odd number?

Answer 1

Answer:

32

Step-by-step explanation:

Possible outcomes in a fair sided die 1,2,3,4,5,6 = 6 possible outcomes

Odd numbers = 1,3,5 = 3 odd numbers

Probability of rolling an odd number = $\frac{3}{6}$ = $\frac{1}{2}$

Total number of rolls = 64

expected number of odd number rolls in 64 roll,

= $\frac{1}{2}$ x 64 = 32
