The probability that the selected contestant received a score of 555 on day 222 or day 333 is 5/7.
If it is given that on day 222 the no of contestants received a score of 555 is 2 and no of contestants received a score of 555 on day 222 is 3.
Given:
It is given that no contestant received the same score on two different days. So, we have 7 days in a week which means there are 7 contestants only who could be chosen and have a score of 555.
So, the contestants who received a score of 555 on any day = 7.
Now, the contestant received a score of 555 on day 222 is 2 and on day 333 is 3.
Probability = No of favorable outcomes/Total no. of outcomes
Probability = (2 + 3)/7 = 5/7
The probability that the selected contestant received a score of 555 on day 222 or day 333 is 5/7.
If it is given that on day 222 the no of contestants received a score of 555 is 2 and no of contestants received a score of 555 on day 222 is 3.
