Question

Can anyone help me fast?

Answer 1

Answer:

0.625

Step-by-step explanation:

From the picture we get to know that the

frequency in 32 = 6

frequency in 31 = 1

frequency in 30 = 4

frequency in 29 = 2

frequency in 28 = 1

frequency in 25 = 1

So, the total frequency that student has a mass at least 32

= ( 6 + 1 + 4 + 2 + 1 + 1 )

= 15

Given total number of student is 24.

Hence the required probability is:

15/24

= 5/8

= 0.625

Answer 2

For at least 32 kg we take mass from 32 to 40 kg so we count dots from 32 to 40 in dot diagram.

6+1+4+2+1+1= 15

so probability=

$\frac{15}{24} = \frac{5}{8}$
