Answer 1

Ответ:

а) 176/200=22/25- шанс не выиграть деньги

б) 190/200=19/20- шанс не выиграть вещь

в) 166/200=83/100- шанс ничего не выиграть

Answer 2

Probability of not winning a cash prize:

To calculate the probability of not winning a cash prize, we need to determine the number of tickets that do not win a cash prize and divide it by the total number of tickets.

Given that there are 200 tickets in total and 24 of them win cash prizes, the number of tickets that do not win a cash prize is 200 - 24 = 176.

Therefore, the probability of not winning a cash prize is 176/200 = 0.88 or 88%.

Probability of not winning a material prize:

Similarly, to calculate the probability of not winning a material prize, we need to determine the number of tickets that do not win a material prize and divide it by the total number of tickets.

Given that there are 200 tickets in total and 10 of them win material prizes, the number of tickets that do not win a material prize is 200 - 10 = 190.

Therefore, the probability of not winning a material prize is 190/200 = 0.95 or 95%.

Probability of not winning any prize:

To calculate the probability of not winning any prize, we need to determine the number of tickets that do not win any prize and divide it by the total number of tickets.

Given that there are 200 tickets in total, the number of tickets that do not win any prize is 200 - (24 + 10) = 166.

Therefore, the probability of not winning any prize is 166/200 = 0.83 or 83%.

Please note that these calculations assume that each ticket has an equal chance of winning and that the prizes are not dependent on each other.
