Answer: 7/8 inches
Step-by-step explanation: There are 3 x's for 1/8 so that is 3/8. There are 2 x's for 1/4 which is 2/4, but you need to have the same denominator so you do 2 times the numerator and denimator which is 4/8. 3/8 + 4/8 = 7/8
Answer:
0.382
0.4
option (a)
Step-by-step explanation:
Formula to calculate probability
a)
probability = number of times event occur / total number of trials
Experimental probability of landing on white = 191/500 = 0.382
b)
probability = favourable outcome / total outcome
Theoretical probability of landing on white = 2/5 = 0.4
c)
As more trials are conducted, the experimental probability generally gets closer to the theoretical probability.
First you find the area of the square which is 8²=64 than you find the area of a circle using the formula πr² you get 201.06 and divide it by 4 because you only need the quarter and you get 50.26 the last step is to add the two areas together and you get 64+50.26=114.2
