Explanation:

When a coin is tossed,

Probability of getting heads = 1/2

Probability of getting tails= 1/2

When two coins are tossed the probability of getting two heads simultaneously is getting heads in first trial and getting head in second trial

P (Getting heads in both trials) \(= \dfrac{1}{2} \times \dfrac{1}{2} = \dfrac{1}{4}\)

Q1.A game consists of spinning an arrow around a stationary disk as shown below. When the arrow comes to rest, there are eight equally likely outcomes. It could come to rest in any one of the sectors numbered 1, 2, 3, 4, 5, 6, 7 or 8 as shown. Two such disks are used in a game where their arrows are independently spun. What is the probability that the sum of the numbers on the resulting sectors upon spinning the two disks is equal to 8 after the arrows come to rest?

Q9.The figure shows the schematic of a production process with machines A, B and C. An input job needs to be pre-processed either by A or by B before it is fed to C, from which the final finished product comes out. The probabilities of failure of the machines are given as: PA = 0.15, PB = 0.05, PC = 0.1. Assuming independence of failures of the machines, the probability that a given job is successfully processed (up to the third decimal place) is ___________.
