Answer:
1/15
Step-by-step explanation:
There are a total of 10 fruits, 3 of which are apples.
The probability that the first selection is an apple is 3/10.
There are now 9 fruits remaining, 2 of which are apples. So the probability that the second fruit is an apple is 2/9.
The total probability is (3/10) (2/9) = 1/15.
Answer:
9500

9500 people are registered to vote.
Answer:
The probability is 0.95
Step-by-step explanation:
In this question, we are interested in calculating the probability that a randomly selected student of the university recycles at least some of the times
Mathematically, the probability that student recycles at least some of time = 1 - probability that the student never recycles all the time
From the question, the probability that the student never recycles all the time = 0.05
Substituting this into the equation given above;
Probability that a randomly selected student at the university recycles at least some of the time = 1-0.05 = 0.95
