Question

The students of a school from VI to X planted 50 plants in various parts of the
school campus. After a month, plants survived which are planted by the students
of different classes are given below:
What is the probability of survival of :
(i) more than 40 plants which are planted by a class?
(ii) 47 plants which are planted by a class?
(iii) less than 40 plants which are planted by a class?
(iv) What value is depicted in the student's act

Answer 1

Step-by-step explanation:

Probability that more than 40 plants which are planted by a class = (class VII and class VII)/Total number of

                                                                                                      classes

                                                                                                  = 2/5

2. Probability that 47 plants which are planted by a class = 0/5 = 0    {since no class has planted 47 plants}

1. Probability that more than 40 plants which are planted by a class = (class IX)/Total number of

                                                                                                      classes

                                                                                                  = 1/5
