What is the probability of getting more than 60 heads in 100 tosses?

On a coin there is 2 sides so there is an even chance so if it’s 50 / 50 you would have to do more than 100 tosses to get over 60 heads

100 coin tosses form a binomial distribution with number of trials = 100 and probability of success = 0.5

The probability of getting more than 60 heads in 100 tosses is P(X > 60), which can be evaluated by summing up the individual probabilities for X = 61 to 100. This gives 0.0176 or 1.76%.

A side of the triangle below has been extended to form an exterior angle of 164". Find

Arada [10]

Given:

Measure of exterior angle = 164°

The measure of opposite interior angles are x° and 53°.

To find:

The value of x.

Solution:

According to the Exterior Angle Theorem, in a triangle the measure of an exterior angles is always equal to the sum of measures of two opposite interior angles.

Using Exterior Angle Theorem, we get

$x^\circ+53^\circ=164^\circ$
