# Two coins are tossed 400 times and we getTwo heads:112 times; one head 160 times ;0 times; 0 head :128 times.When two coins are tossed at random, what is the probability of getting(i) 2 heads? (ii) 1 heads? (iii) 0 head?

Total number times coin tossed: 400

Number of times Two heads occurred: 112

Number of times One head occurred: 160

Probability P()=

(i). Let p(H1) be probability of getting Two heads

P (H1) =

P (H1) = = 0.28

(ii). Let p(H2) be probability of getting One head

P (H2) =

P (H2) = = 0.4

(iii). Let p(H3) be probability of getting No head

P (H3) =

P (H3) = = 0.32
