URGENT HELP)

Shari rolls a pair of dice, numbered 1 to 6, 64 times. How many times can she expect to roll an odd number!

Answer 1

32

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 =
`(3)/(6)` =
`(1)/(2)`

Total number of rolls = 64

expected number of odd number rolls in 64 roll,

=
`(1)/(2)` x 64 = 32
