Determine if the following is mutually exclusive (Disjoint) or overlapping and then calculate the probability. A card is randomly selected from a standard deck of 52 playing cards. What is the probability that it is a 10 or a spade?

Step-by-step explanation:

GIVEN: Determine if the following is mutually exclusive (Disjoint) or overlapping and then calculate the probability. A card is randomly selected from a standard deck of   playing cards.

TO FIND: What is the probability that it is a or a spade.

SOLUTION:

getting a and getting a spade are not disjoint events as both can occur simultaneously.

Now probability of getting a spade

probability of getting a

probability of getting a and a spade

probability of getting a or a spade

probability that it is a 10 or a spade is

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
