प्रश्न
Two coins are tossed simultaneously 300 times and the outoomes are noted as :
Two tails : 83
Ole tail :140
No tai :77
Find the probabiity of Occurrence of each of these events.
उत्तर
Number of times 2 tails come up = 83
Total number of times the coins were tossed = 300
P(2 tails will come up) = `"Number of times 2 tails come up"/"Total number of times the coins were tossed"`
= `83/300`
Number of times 1 tail come up = 140
Total number of times the coins were tossed = 300
P(1 tail will come up) = `"Number of times 1 tail come up"/"Total number of times the coins were tossed"`
= `140/300 = 7/15`
Number of times no tail come up = 77
Total number of times the coins were tossed = 300
P(no tail will come up) = `"Number of times no tail come up"/"Total number of times the coins were tossed"`
= `77/300`
