A)31.25%
B)35.7%
C)50%
D)62.5%
E)66.7%

Answer 1

Answer:

The probability the Rams scored at least 20 points is 62.5%

Step-by-step explanation:

Data form histogram:

No. of points                        No. of games

0-9                                                 2

10-19                                              4

20-29                                            5

30-39                                            3

40-49                                            2

Now we are supposed to find the probability the Rams scored at least 20 points

So, we are supposed to find the probability the Rams scored 20 or more than 20

So, Total no. of games = 2+4+5+3+2=16

No. of games where score is 20 or more than 20 =5+3+2 = 10

So,  the probability the Rams scored at least 20 points = $\frac{10}{16}=0.625$

So, the probability the Rams scored at least 20 points is 62.5%

Hence Option D is true .
