Question

A die is rolled 200 times and its outcomes are recorded as below: Outcomes:1,2,3,4,5,6 Frequency:25,35,40,28,42,30 Find the probability of getting: 1) an even prime 2) a multiple of 3

Answer 1

Emperical probability =no.of events occured/Total no.of events
1)Epno.of times even primes occured/total no.of occurance
=frequency of 2/200
=35/200
=7/40//

2)Ep=no.of times a multiple of 3 occured/ total
no.of events
=frequency of 3+6/200
=40+30/200
=70/200
=7/20//

HOPE IT HELPS
IF SO PLS HELP ME BY GIVING BRAINLIEST.....

Answer 2

Total = 200
1). p( an even prime ) = 2/200
= 1/100

2). p ( a multiple of 3 ) = 3+6/200
= 40+30/200
= 70/200 = 7/20

hope dis ans helps u:)
mark me as brainliest plz..
