Find the measure of angle PQR

Help me please

Given that the

We need to determine the measure of ∠PQR

Measure of ∠PQR:

The measure of ∠PQR can be determined using the formula,

The measure of the arc PSR can be determined by subtracting the arc PR with 360°

Thus, we have;

Now, Substituting , in the formula, we have;

Thus, the measure of ∠PQR is 49°

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
