What is the probability of getting a 10 or a jack from a deck of poker cards (52 cards)?
krek1111 [17]

Answer:

15.38%

Step-by-step explanation:

there are four 10 cards and four jack cards.

4+4=8

you want to get one from 52 cards, so it's 8 out of 52. 8/52

to calculate the percentage, you multiply 8 by 100, then divide by 52.

8*100/52=15.38 (rounded answer)
