In a certain math class, it is known that 18 students LOVE math review, and 5 students dislike math review. The teacher randomly selects three students from the class. What is the probability that all three students love math review?

Answers

The probability that the first random choice will be a matho-file and not a -phobe is 18/23. The probability of the second one is 17/22, and for the third one it's 16/21. The probability of all 3 is 4,896/10,626 = (18x17x16)/(23x22x21). That's 46.1% (rounded).

Question 2 (Multiple Choice Worth 6 points)(09.03 LC)

Tanya drives to work every day and passes two independently operated traffic lights. The probability that both lights are red is 0.55. The probability that the first light is red is 0.69. What is the probability that the second light is red, given that the first light is red?
0.83
0.75
0.80
0.73

Answers

Answer:

Step-by-step explanation:

Let the probability that the first light is red is= $P_(1)$ and

the probability that the second light is red= $P_(2)$ . Then,

Probability that both lights are red= $P( P_(1) and P_(2) )$ = 0.55,

Probability that the first light is red= $P(P_(1))$ =0.69,

Probability that the second light is red, given that the first light is red= $P( P_(2) /P_(1))$ = $(P(P_(1) and P_(2)) )/(P(P_(1)) )$

= $(0.55)/(0.69)$

= $0.7971$

≈ $0.80$

Given:
Probability that both lights are red 0.55
Probability that 1st light is red 0.69

Find the probability that the 2nd light is red, given that the first light is red.

0.55/0.69 = 0.797 or 0.80

The probability that the 2nd light is red while the 1st light is also red is 0.80.
