Ответ:
B. 4/75
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
For each trial:
The probabilities of picking each startbust are the same, so each event is independent.
Independent events:
Two events, A and B, we have that:
In this question:
Event A: Yellow starburst on the first trial.
Event B: Orange starbust on the second trial.
4 yellow out of 5+4+3+3 = 15 starbursts.
This means that![P(A) = \frac{4}{15}](/tpl/images/0671/6749/a1927.png)
3 orange out of 15 starbursts.
This means that![P(B) = \frac{3}{15}](/tpl/images/0671/6749/a2ca0.png)
