# A coin is loaded so that the probability of heads is 0.7 and the probability of tails is 0.3. Suppose that the coin is tossed ten times and that the results of the tosses are mutually independent. What is the probability of obtaining exactly seven heads? What is the probability of obtaining exactly ten heads? What is the probability of obtaining no heads? What is the probability of obtaining at least on one head?

To determine

(a)

To find out the probability of obtaining exactly seven heads.

Explanation

Given information:

The probability of heads is 0.7 and the probability of tails is 0.3. The coin is tossed ten times and results of tosses are independent.

Calculation:

According to the given information the following things can be written

P(H)=0.7P(T)=0

To determine

(b)

To find out the probability of obtaining exactly ten heads.

To determine

(c)

To find out the probability of obtaining exactly no heads.

To determine

(d)

To find out the probability of obtaining at least one head.
