Question

You flip a coin, toss a number cube, and then flip another coin. What is the probability that you will get heads on the first coin, a 3 or a 5 on the number cube, and heads on the second coin?

Answer 1

Probility is `1/12 or 8.33(2dp)%`

Explanation:

Possible outcome on first coin is `2`
favourable outcome on a first coin is `1`
So probability is `1/2`

Possible outcome on number cube is `6`
favourable outcome on number cube is `2`
So probability is `2/6=1/3`

Possible outcome on second coin is `2`
favourable outcome on second coin is `1`
So probability is `1/2`

So Probility is `1/2*1/3*1/2=1/12 or 8.33(2dp)%` [Ans]
