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:
The correct answer is not shown in your picture. You must get a = 60.
Step-by-step explanation:
(1/2)a + (2/3)b = 50
b = 30
(1/2)a + (2/3)(30) = 50
(1/2)a + 20 = 50
(1/2)a + 20 - 20 = 50 - 20
(1/2)a = 30
2 * (1/2)a = 2 * 30
a = 60
The correct answer is not shown in your picture. You must get a = 60.
