Question

Harpreet tosses two different coins simultaneously (say, one is of ` 1and other of ` 2). What is the probability that she gets at least one head?

Answer 1

In single throw of two coins....

Total possible outcomes= 4 (HH,TH,HT,TT)

favourable outcomes= 3

$p(e) = \frac{favourable \: outcomes \: }{total \: possible \: outcomes}$

$p(at \: least \: one \: head) = \frac{3}{4}$

$\textbf{so probability is \frac{3}{4}}$
