The probability that all marbles are yellow is
(7/20) (7/20) (7/20) = 343/8000
We are given
x = 2 and 3
u = 2.5
s = 0.5
Getting the z score
z = (2 - 2.5) / 0.5 and (3 - 2.5)/ 0.5
z = -1 and 1
The percentage is
1 - 0.1557 = 81.5%
Answer:
The answer is C. 3x+y=7, 6x+2y=10
Step-by-step explanation:
12.5%. there is a 1 in 8 chance that all three times it will land on heads.
72 m is the surface area because you multiply L × W × H, which is 6 × 4 ×3 = 72
First add the biggest number like thousand together and the go in to the last numbers
