Probability problem 3

A fair coin is tossed 450 times and the outcomes were noted as: Head = 250, Tail = 200.

Find the probability of the coin showing up 

(i) a head

(ii) a tail.

Solutions

Expert Solution

Number of times coin is tossed = 450

 

Number of heads = 250

 

Number of tails = 200

 

(i) Probability of getting a head

 

  P(H) =Number of favorable outcomes /Total number of possible outcoms

     = 250/450

      = 5/9

(ii) Probability of getting a tail

 

  P(T)=   Number of favorable outcomes/Total number of possible outcomes

      = 200/450

      = 4/9

P(T)=5/9

P(H)=4/9
