1.	Two coins are tossed 1000 times and the outcomes are recorded as below :Based on this information, the probability for at most one head is(A) 1/5(B) 1/4(C) 4/5(D) 3/4
Answer» (C) 4/5 The total number of coins tossed, n(S) = 1000 Number of outcomes in which atmost one head, n(E) = 550 + 250 = 800 =n(E)/n(S) = 800/1000 = 4/5 Hence, the probability for atmost one head is 4/5 .

Answer»

(C) 4/5

The total number of coins tossed, n(S) = 1000

Number of outcomes in which atmost one head,

n(E) = 550 + 250 = 800

=n(E)/n(S) = 800/1000 = 4/5

Hence, the probability for atmost one head is 4/5 .
