Question

Kim rolls a dice and flips a coin. a) calculate the probability that she gets a 2 and a head

Answer 1

Kim rolls a dice and flips a coin.

For coin: we have either H or T

For dice: we have 1, 2, 3, 4, 5 or 6

On a coin, the probability of heads:
`(1)/(2)`

On a dice, the probability of getting 2 :
`(1)/(6)`

Hence, the probability of getting a 2 and a head is

`(1)/(2)*(1)/(6)` =
`(1)/(12)`

So, the probability that Kim gets a 2 and a head is
`(1)/(12)`
