Answer:

  -29/20

Step-by-step explanation:

M drives past two traffic lights. Probability that both are red is .35 and probability that firest is red is .48. wht is probabi
snow_lady [41]

Answer:

Step-by-step explanation:

Overall probability = Probability1 *Probability2

Using the data you already have, you can fill it in as

0.35 = 0.48 * P2

Rearrange to isolate P2, by dividing both sides by 0.48, so

0.35/0.48 = P2

P2 = 0.7291666..., which rounded to two d.p is 0.73

So d)0.73 is correct
