Answer:

a) P = 0.125

b) It is not necessarily true

Step-by-step explanation:

a. If the coin was fair, the probability of obtaining head would be 0.5, and each launch of the coin would be an independent event.

Remember that if two events A and B are independent, then:

P(A∩B) = P(A)P(B)

Therefore, the probability that Caitlin would get heads on all three flips is:

P(A∩A∩A) = P(A)P(A)P(A) = 0.5*0.5*0.5 = 0.125

b) It is not necessarily true, because there exist a probability associated to this event and it means that this situation can occur although the coin was fair.

A girl scout was selling boxes of cookies. In a month, she sold both boxes of chocolate chip cookies ($1.25 each) and boxes of p
Katena32 [7]

Answer:

Number of plain cookie boxes sold = 785 boxes

Step-by-step explanation:

Given: Cost of a chocolate chip cookie box = $1.25

Cost of a plain cookie box = $0.75

Total number of boxes sold = 1585

Total cost of the sold boxes = $1588.75

Let, number of plain cookie boxes sold = x

Number of chocolate chip cookie boxes sold = 1585 - x

So,

Total cost = total cost of the sold plain cookie boxes + total cost of the sold chocolate chip cookie boxes

$1588.75 = x ($0.75) + (1585 - x) ($1.25)

1588.75 = 0.75 x + 1981.25 - 1.25 x

0.5 x = 392.5

Therefore,

<u>Number of plain cookie boxes sold: x = 392.5 ÷ 0.5 = 785 boxes</u>
