Assume the random variable X follows a Binomial Distribution with number of trial n and probability of success p. The probability mass function of the distribution is give as follows: P(X = x) = Qp*q"-, x = 0,1,2,..,n. Il y = 1-p Then show that E(X) = np and V(X) = npq. ​

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
