Question

13. In Q.1, Exercise 14.2, you were asked to prepare a frequency distribution table regarding
of 30 students of a class. Use this table to determine the probability
that a student of this class, selected at random, has blood group AB.
groups
the blood
​

Answer 1

Answer:

Step-by-step explanation:

The blood groups of 30 students of class VIII are recorded as follows

A, B, 0, 0, AB, 0, A, 0, B, A, 0, B, A, 0, 0, A, AB, 0, A, A, 0, 0, AB, B, A, B, 0

You were asked to prepare a frequency distribution table regarding the blood groups of 30 students of a class. Use this table to determine the probability that a student of this class, selected at random, has blood group AB.

Solution:

Here, total number of students = 30

∵ Number of students having blood group AB = 3

∴ Probability of a student whose blood group is AB = 3 = 1

                                                                                        30  10

Answer 2

Answer:

total -30

p(AB)=3/30=1/10

Step-by-step explanation:

I think so three will cut then comes one.

and 30 will cut it comes ten then answer will come

one upon ten

1/10
