Question

Two coins throw a one time. Find the probability of getting (i) maximum 2 heads (ii) minimum 1 tail.​

Answer 1

Answer:

(i) 1

(ii) 3/4

Step-by-step explanation:

If we throw 2 coins to gather, we have following results,

HH, TT, HT, TH

(i) Maximum 2 heads means not more than 2.

so we have to find 0 head, 1 head and 2 head from our above results

so we get TT, HT, TH, HH.

So probability for this is = 4/4 = 1

(ii) Minimum 1 tail means not less than 1.

so we have to find 1 tail and 2 tails from our above results

so we get HT, TH, TT

So probability for this is = 3/4
