A coin is tossed 80 times with following outcomes:
Head: 35 times and tail: 45 times.
In a single throw of a coin, if E be the event of getting a head, verify that p (E) +P(not E)=1.
Total number times a coin is tossed = 80
Number of times head occurred = 35
Number of times tail occurred = 45
Probability P() =
Probability of getting a head is P(head) =
Probability of getting a tails is P(tail) =
Here P(head) = and P(tail) =
Now, P(head) + P(tail)
