a)

b)

c)

Step-by-step explanation:

Given : Two cards are selected from a regular deck of cards. If the first was a ten.

To determine : The probability that the second was a (a) ten, (b) jack, (c) picture card ?

Solution :

Total number of cards = 52 in which there are 4 sets of 13 cards with two different color.

We are drawing two card one after another without replacement.

Probability of drawn first card 10 is

a) Second card drawn is 10,

Probability of drawn second card 10 is

Total probability that first card was 10 and second card is 10,

b) Second card drawn is Jack,

Probability of drawn second card Jack is

Total probability that first card was 10 and second card is Jack,

c) Second card drawn is picture card,

Number of picture card is 4j's, 4Q's, 4K's = 12

Probability of drawn second card picture card is

Total probability that first card was 10 and second card is picture card,

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
