What is the value of 10C3?
Zigmanuir [339]
The answer is B. 120

nCr = n! / ((r! * (n - r)!)

n = 10
r = 3

10C3 = 10! / ((3! * (10 - 3)!)
         = 10! / ((3! * 7!)
         = (10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) / (3 * 2 * 1 * 7 * 6 * 5 * 4 * 3 * 2 * 1)
         = 3628800 / 30240
         = 120

The waiting time, in hours, between successive speeders spotted by a radar unit is a continuous ran- dom variable with a cumulat
enyata [817]

Answer: 0.5507

Step-by-step explanation:

Given : The waiting time, in hours, between successive speeders spotted by a radar unit is a continuous random variable X with a cumulative distribution function

F(x)= \begin{cases}0,& x

Since , the waiting time is in hours , then we can write 12 minutes as \dfrac{12}{60} hour i.e.0.2 hour.

Now, the probability of waiting fewer than 12 minutes between successive speeders is given by :-

P(X

Hence, the required probability = 0.5507
