1.	Two coins are tossed simultaneously. What is the probability of getting at least one head?
Answer» Total numbers of elementary events are 2+ 2 = 4 Let E be the event of getting at least two heads The favorable outcomes are: HH, HT, TH Total numbers of favorable outcomes are 3 P (ATLEAST one head) = P (E) = \(\frac{3}4\) Note: at least one head means the outcome with one head or more will be considered favorable and the outcome with no head at all will be ruled out.

Answer»

Total numbers of elementary events are 2+ 2 = 4

Let E be the event of getting at least two heads

The favorable outcomes are: HH, HT, TH

Total numbers of favorable outcomes are 3

P (ATLEAST one head) = P (E) = \(\frac{3}4\)

Note: at least one head means the outcome with one head or more will be considered favorable and the outcome with no head at all will be ruled out.
