The probability is 0.1429.
The probability that the first person chosen is a boy is 5/7. The probability that the second is a boy is 4/6; the third, 3/5; and the fourth, 2/4. Both the numerator and denominator decrease every time, because you lose a boy to choose from and you lose a student to choose from as well. This gives us:
5/7(4/6)(3/5)(2/4) = 120/840 = 0.1429.

Answer:
Yes
Step-by-step explanation:
We know that 1.39 is less than 1.5 and 3.75 is less than 4.
Hence the price of 3.75kg is going to be less than: 4*1.5=$6
Given that apples cost $1.39 per kilogram, then the price of 3.75 kg of apples is 3.75*1.39=$ 5.2125.
Because 5.2125 is actually less than $6
This means that $6 can buy 3.75 kg of apples.
