<h3>The probability that a randomly selected person likes cookies with chocolate or peanut butter chips is 0.77.</h3>
Step-by-step explanation:
Here, the total sample of people has total 535 people.
The percentage of people liking chocolate chip cookies = 65%
Now, 65% of 535 =
⇒ 348 people in total like chocolate chip cookies.
⇒ n(C) = 348
The percentage of people liking peanut butter chip cookies = 37%
Now, 37% of 535 =
⇒ 198 people in total like peanut butter chip cookies.
⇒ n(B) = 198
Percentage of people liking both chocolate &peanut butter chips = 25%
Now, 25% of 535 =
⇒ 134 people in total like both chocolate &peanut butter chips
⇒ n(C ∩ B ) = 134
Now, n( C U B) = N(C) + n(B) - n(C ∩ B )
= 348 + 198 - 134 = 412
P( person likes cookies with chocolate or peanut butter chips)
=
Hence, the probability that a randomly selected person likes cookies with chocolate or peanut butter chips is 0.77.
Answer:
1.92%
Step-by-step explanation:
The probability for first case, picking a queen out of deck, will be:
as there will be 4 queens in a deck, one of each suit.
For the second pick, the probability of picking a diamond card, will be:
here the total will remain 52 as he has replaced the first card and not kept it aside and there will be 13 cards in diamond suit (including the three face cards).
Thus the net probability for both cases will be:
Thus total probability for the combined two cases will be 1.92%
