Question

The weights of the following students are given below :
weights ( in kg ) 44 ; 46 ; 48 ; 50 ; 51 ; 52
no. of students 7 ; 6 ; 9 ; 10 ; 11 ; 12
find the probability that the students having weights more than 46kg

Answer 1

Answer:

55/9 is the probability.

Answer 2

The probability that the students having weights more than 46kg is $\dfrac{42}{55}$

Step-by-step explanation:

Total Number of students = 7+6+9+10+11+12

Total Number of students = 55

Number of students having weights more than 46kg = 9+10+11+12 = 42

probability that  students having weights more than 46kg  =

$\dfrac{\textrm{total number of students above 46kg}}{\textrm{total number of students}}$

= $\frac{42}{55}$

probability that  students having weights more than 46kg = $\dfrac{42}{55}$
