Answer:
Q7 0.2
Q8 0.17
Explanation:
Probability is the ratio of the number of possible outcome to the number of total outcome. The probability that an event will happen when added to the probability that it will not happen is 1
Given that the probability that the bulb will grow is 0.8, the probability it would not grow
= 1 - 0.8
= 0.2
A match may be won lost or drawn
Given that the probability of a win is 0.28 and that of a draw is 0.55, the probability of a loss
= 1 - (0.28 + 0.55)
= 0.17
