Using the cosine rule, the measure of the triangles is a = 51, b = 21, c = 68, A = 30.37°, B = 12.02° and C = 137.61°

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Cosine rule is given as:

a² = b² + c² - 2bc * cosA

Given that a = 51, b = 21, c = 68, hence:

51² = 21² + 68² - 2(21)(68) * cosA

A = 30.37°

21² = 51² + 68² - 2(51)(68) * cosB

B = 12.02°

68² = 21² + 51² - 2(21)(51) * cosC

C = 137.61°

Using the cosine rule, the measure of the triangles is a = 51, b = 21, c = 68, A = 30.37°, B = 12.02° and C = 137.61°

What is the probability of flipping exactly 6 heads when you flip 6 coins? Please explain your answer and those who waste an ans
kolbaska11 [484]

Binomial probability states that the probability of x successes on n repeated trials in an experiment which has two possible outcomes can be obtained by

(nCx).(p^x)⋅((1−p)^(n−x))

Where success on an individual trial is represented by p.

In the given question, obtaining heads in a trial is the success whose probability is 1/2.

Probability of 6 heads with 6 trials = (6C6).((1/2)^6).((1/2)^(6–6))

= 1/(2^6)

= 1/64
