The probability that tomorrow's temperature will be average is 55%. The probability that the temperature will be above average is 25%. Work out the probability that the temperature will be BELOW average

Probability that the temperature below average = 20%

Step-by-step explanation:

Given:

Probability that tomorrow's temperature average = 55%.

Probability that the temperature above average = 25%

Find:

Probability that the temperature below average

Computation:

Probability that the temperature below average = 100% - Probability that tomorrow's temperature average - Probability that the temperature above average

Probability that the temperature below average = 100% - 55% - 25%

Probability that the temperature below average = 100% - 80%

Probability that the temperature below average = 20%

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 %  

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
