Question

Francisco is playing a game with 3 green, 2 yellow, 4 red, and 3 black marbles in a bag. He has calculated the probability of drawing a yellow marble, not replacing it, and then drawing a red marble. Explain the error in his solution.

Answer 1

Step-by-step explanation:

Favorable outcomes for orange marbles = 2

Total no. of outcomes = 9

Probability,P(E) = Number of outcomes favorable to E

Number of all possible outcomes of the experiment

P (Picking an orange marble) =29

∴P (not picking an orange marble) =1−29

=79
