Answer: Answer: 1/24

---------------------------------------------------------------------

---------------------------------------------------------------------

Work Shown:

A = selects green pair of shorts

B = selects gray t-shirt

P(A) = probability of selecting green shorts

P(A) = (number of green shorts)/(number of shorts total)

P(A) = 1/6

P(B) = probability of selecting gray t-shirt

P(B) = (number of gray t-shirts)/(number of t-shirts total)

P(B) = 1/4

P(A and B) = probability of selecting green shorts AND gray t-shirt

P(A and B) = P(A)*P(B) ... since A and B are independent events

P(A and B) = (1/6)*(1/4)

P(A and B) = (1*1)/(6*4)

P(A and B) = 1/24

Note: The fraction 1/24 is approximately equal to 0.041667

What is the product of 3y^-4 times 2y^-4?

Answer:

Product of 3y^-4 and 2y^-4 is 6y^-8

Step-by-step explanation:

Given,

3y^-4 and 2y^-4

Product of 3y^-4 and 2y^-4

i.e 3y^-4 * 2y^-4

or 3*2*y^(-4-4)

or 6y^-8

Hence we get product of 3y^-4 and 2y^-4 is 6y^-8
