Question

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. 

Answer 1

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`
