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:

**Answer:**** Option A **

**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.

**Answer:**** Option D **

=> 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
