Answer: The probability for both is 1/2
Step-by-step explanation:
For A. The probability for who do or do not participate in some kind of sport is found by adding the students who do or do not. Which is 25 + 225 = 250
250 out of 500 simplified is 1/2
For B. The probability got who do and do not participate in some kind of sport is found by taking the number of students out of the whole number. Its 250 out of 500.
250 out of 500 is simplified to 1/2.
Answer: Let x = the length of a side of the square
a2 + b2 = c2
x2 + x2 = 102
2x2 = 100
x2 = 50
x = √50
x = 5√2 cm
