Answer:
The probability that the second card is a face card if it’s known that the first card was a face card is 0.0497
Step-by-step explanation:
Total number of face cards = 12
Total cards = 52
Probability of getting face card on first draw=
Remaining no. of face cards = 11
Remaining number of total cards = 51
Probability of getting face card on second draw=
The probability that the second card is a face card if it’s known that the first card was a face card =
Hence The probability that the second card is a face card if it’s known that the first card was a face card is 0.0497
48 cookies after 25 % decrease is as much as 75 % from 48:
75% from 48 =
= 75/100 * 48 =
= 3/4 * 48 =
= 3/1 * 12 =
= 3 * 12 =
= <u>36
