Box A and Box B each contain blue and green pens only. Raphael pick a pen at random from box A and pulao pick a Pen at random from Box B. the probability that Raphael picks a blue pen is 2/3. the probability that both Raphael and pulao pick a blue pen is 8/15 b) find the probability that both raphael and pulao pick a green pen

1/15

Step-by-step explanation:

Picking from two different bags are independent trials

P(pulao picks Blue) × 2/3 = 8/15

P(pulao picks Blue) = 4/5

Raphael picks green: 1 - ⅔ = ⅓

Pulao picks green: 1 - ⅘ = ⅕

Both pick green: ⅓ × ⅕ = 1/15

40 * 8 + (1.5 * 8)(x - 40) = gross x being hrs worked

for 50

320 + 12(x - 40) = gross pay

320 + 12(50 - 40) =  

320 + 12(10) =  

320 + 120 =  

440 = gross pay
