Find the probability that a randomly selected card from a Euchre deck is a jack or a spade. (Enter the fraction reduced to the lowest possible fraction on the left hand side of "=" symbol and the final answer on the right hand side simplified to the lowest possible fraction.)

3/8

Step-by-step explanation:

There are 24 cards in a euchre deck with 4 Jack and 6 spade

P (J U S) = 4/24 + 6/24 - 1/24 = 1/6 + 1/4 - 1/24 = 3/8

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
