Answer:
A. 1/2.
B. 15/26.
Step-by-step explanation:
Note when you have an 'OR' in the statement we add the probabilities.
A . Club or a diamond . There are 13 clubs and 13 diamonds so
The Required Probability = 13/52 + 13/52
= 1/4 + 1/4 = 1/2.
B. There are 4 jacks and 26 black cards.
The Required Probability = 4/52 + 26/52
= 1/13 + 1/2
= 2/26 + 13/26
= 15/26.
The probability of picking a club or a diamond is 1/2.
The probability of picking a jack or a black card is 15/26.
- Number of clubs = 13
- Number of diamonds = 13
- Number of jacks = 4
- Number of black cards = 26
The probability of picking a club or a diamond will be:
= 13/52 + 13/52
= 26/52
= 1/2
The probability of picking a jack or a black card will be:
= 4/52 + 26/52
= 15/26
