Question

Two unbiased coins are tossed simultaneously.Find the probability of getting ` (i) At most two heads `
tell me correct plz​

Answer 1

Step-by-step explanation:

'Atmost' means the number of heads should not exceed 2.

Total no. of outcomes when two unbiased coins are tossed=HH ,HT, TH, TT=4

No. of favourable outcomes=HH ,HT ,TH ,TT=4

(We have to include TT because no. of heads can range between 0-2)

Therefore,Probability=(Favourable outcomes/Total outcomes)

=4/4=1 ans.
