Question

You are dealt one card from a 52 card deck find the probability that you are dealt a seven or a black card

Answer 1

57.6%

Explanation:

There are four cards with a 7 and 26 cards that are black.

`4+26=30`

• There are 30 cards that are either black or have a 7 on it.

Divide the desired outcomes (30) by the number of all events (52)

`(Desired Outcome)/(TotalEvents) = (30)/(52) = 0.576= 57.6%`

So there is a 57.6% that there you would be delt a card that is black or a card that have a 7.
