Question

A fair coin is tossed 2 times in succession. the set of equally likely outcomes is (hh,ht,th,tr). find the probability of getting a head on the first toss

Answer 1

The probability of getting a head on the first toss of a fair coin tossed 2 times in succession is 0.5.

Step-by-step explanation:

The probability of getting a head on the first toss of a fair coin tossed 2 times in succession can be found by examining the sample space of possible outcomes. In this case, the sample space is {HH, HT, TH, TT}.

Out of these four outcomes, two of them have a head on the first toss: HH and HT. Therefore, the probability of getting a head on the first toss is 2/4, which simplifies to 1/2 or 0.5.
