a. The probability that the next scarf will be orange will be 1/5.
b. The probability of getting the ace or spades will be 17/52.
c. The probability of getting a king, queen, or jack will be 3/14.
How to calculate the probability?
a. The bag contains 3 blue scarves, 1 red scarf, 5 green scarves, and 2 orange scarves. The probability that the second scarf will be orange will be:
= 2/(3 + 5 + 2)
= 2/10
= 1/5
B. When a card is drawn at random from a deck of cards, the probability of getting the ace or spades will be:
Total number of cards withe the ace = 52
Total number of ace = 4
Number of spade = 13
The probability will be:
= 4/52 + 13/52
= 17/52
C. The probability of getting a king, queen, or
jack will be:.
= 4/52 + 4/52 + 4/52
= 12/52
= 3/14
