3. if there were less than 3 acute angles, the triangle would be either obtuse or right.
Answer: 0.79 or 79%
Step-by-step explanation:
Given : The probability that the athletes are football players : P(A)=0.33
The probability that the athletes are basketball players: P(B)=0.66
The probability that the athletes play both football and basketball : P(A∩B)=0.20
Now, the probability that the athlete is either a football player or a basketball player is given by :-

Hence, the probability that the athlete is either a football player or a basketball player = 0.79
Or we can write it as 79%.
What is the median of the set 1,5,8,10,11,12,14,17,19,21,22,23?
Ilia_Sergeevich [38]
The median of this set is 13.
Explanation: we have 12 numbers, so we take the number between number 6 and 7 which are 12 and 14, between 12 and 14 we got 13, so that’s the median.
