Four cards are drawn from a standard deck. no cards are returned.

a) which is more likely:
• event a: drawing a straight (four consecutive cards e. g. 5, 6, 7, 8)?
• event b: drawing four consecutive queens?
b) explain how does your answer change if cards are returned after each draw?

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
