  • A bag contains slips numbered from 1 to 100. If Fatima chooses a slip at random from the bag, it will either be an odd number or an even number. Since this situation has only two possible outcomes, so, the probability of each is 1 by 2 . Justify.

A bag contains slips numbered from 1 to 100. If Fatima chooses a slip at random from the bag, it will either be an odd number or an even number. Since this situation has only two possible outcomes, so, the probability of each is \frac{1}{2} . Justify.

Answer.       [True]
Solution.         Probability: probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Total slips = 100
Slips with even number = 50
Probability = \frac{Number\, of\, favourable\ cases }{Total\, number\, of\, cases}
Probability of slip with even number = \frac{50}{100}= \frac{1}{2}
Slips with odd number = 50
Probability of slip with odd number = \frac{50}{100}= \frac{1}{2}
Hence the probability of each is \frac{1}{2} .
