# Two coins are tossed 1000 times and the outcomes are recorded as given below: In a simple throw of two coins, what is the probability of getting(i) at most one head? (ii) At least one head?

Total number times a coin is tossed = 1000

Number of times no heads occurred = 240

Number of times one head occurred = 450

Number of times two head occurred = 310

Probability P() = (i) Probability of getting at most one head is (that is Probability of no head and one head)

P( at most one head) = (ii) Probability of getting at least one head is (that is Probability of one head and two head)

P( at least one head) = Rate this question :
