Question

Gill rolls a number cube 78 times how many times can he expect to roll an odd number greater than 1 ?

Answer 1

the die has 6 numbers therefore it is a probability that a number has a 17% drop then if we throw it 78 times each die can fall 13 times if you multiply 13 by 6 it will give you 78 therefore they fall 26 times because there are only two odd numbers 3 and 5 larger than 1 each falls 13 times we add it and gives 26 the answer is (26)

Answer 2

There are 6 numbers on a dice: 1, 2, 3, 4, 5, and 6.

If you roll the dice once, you have a 5/6 chance of rolling a number higher than 1. To roll an odd number higher than 1 (3 and 5) you have a 2/6 chance, rounded to a 1/3 chance.

Multiply 1/3 and 78 = 26

You can roll the dice 78 times and get an odd number higher than 1 26 times.

Hope this helps :)
