Question

the probability of scoring marks more than 50 and not more than 58 in a 100 marks paper by a student is​

Answer 1

Answer:

1st). 1/2

2nd). 29/50

Step-by-step explanation:

•let E be the probability of scoring marks more than 50

here I'm using probability formula

p(E)=n(E)/n(S)

n(E)= 50

n(S)=100

p(E)=?

substitute the value in the formula.

p(E)=50/100

p(E)=1/2

•let E be the probability of not scoring more than 58

n(E)=58

n(S)=100

p(E)=58/100

cancel with 2 table

p(E)=29/50
