Answer:

B. The probability of getting a red convertible is 0.10.

Step-by-step explanation:

Independent events:

Two events, A and B, are independent if the probability of both happening is the same as the multiplication of the probabilities of each happening, that is:

P(A \cap B) = P(A) \times P(B)

In this question:

Event A: Red car -> 0.25 probability

Event B: Convertible car -> 0.4 probability

Independent if:

The probability of getting a red convertible car is:

P(A \cap B) = P(A) \times P(B) = 0.25*0.4 = 0.1

Thus, the correct answer is given by option B.

dlinn [17]

Answer:

1/15

Step-by-step explanation:

7+3 = 10 items in the bag

P(grape) = grapes/total

                3/10

No replacement

7 cherries 2 grapes = 9 items

P(grape) =  grapes/total

                    2/9

P(grape, no replacement, grape) = 3/10*2/9

                                                       =1/15
