44. In a class, there are 15 boys and 10 girls. Three students are selected at random. The probability that 1 girl and 2 boys are selected, is:

Explanation:

Let's assume the sample space = S
and Event of selecting 1 girl and 2 boys = E

So, n(S) = Number ways of selecting 3 students out of 25 = 25C3
=> (25 * 24 * 23)/(3 * 2 * 1) = 2300.
n(E) = (10C1 * 15C2)
= 10 * [(15 * 14)/(2 * 1)] = 1050.
P(E) = n(E)/n(S) = 1050/2300 = 21/46.

46. If 3√5 + √125 = 17.88, then what will be the value of √80 + 6√5

Explanation:

3√5 + √125 = 17.88
=> 3√5 + √25√5 = 17.88
=> 3√5 + 5√5 =17.88
=> 8√5 = 17.88 => √5 = 2.235

√80 + 6√5
=> √16√5 + 6√5
=> 4√5 + 6√5
=> 10√5

So 10 * 2.235 = 22.35
