Emily has a coin with P(H) = pi and Pete has a coin with P(H) = P2. Emily tosses her coin n times, and denote the number of head
s by X. Now Pete tosses his coin X times. What should be the distribution of the number of heads that Pete gets? Try to answer this question from two different approaches.
(a) Answer this question by constructing suitable binomial experiments.
(b) Answer this question by direct calculation. This is a challenging task. Hint: Try to use the binomial expansion xkym-k = (x + y)", k k=o. which holds for ALL positive integers m and real numbers x, y.

The length is given 15 feet and the width is 12 feet...Now let's find the Perimeter..
- The formula to calculate Perimeter of rectangle is 2 ( l + b )
Perimeter = 2 ( l + b )
= 2 ( 15 + 12 )
= 2 × 27
= 54 feet

The type of numbers, rational and irrational from the numbers Keisha writes are;
a. Rational numbers; -9, 3.0, 2, and 2.42
b. Irrational numbers; √8
<h3>What is the difference between rational and irrational numbers?</h3>Rational numbers are numbers are numbers that can be expressed as a ratio of two whole numbers P/Q, in which, <em>Q </em>≠ 0
Irrational numbers are those that cannot be expressed as a fraction P/Q
The given numbers are;
-9, √8, 3.0, 2, 2.42
- -9 = -9/1
- √8 = 2•√2 (√2 cannot be expressed as a fraction of two whole numbers)
- 3.0 = 3/1
- 2 = 2/1
a. The rational numbers are therefore;
- -9, 3.0, 2, and 2.42
b. The irrational number is; √8
