<h3>
Answer: 45/121</h3>
=========================================
Work Shown:
2 blue, 4 red, 5 green
2+4+5 = 11 total
P(blue) = probability of getting one blue marble
P(blue) = (number of blue)/(number total)
P(blue) = 2/11
A = P(2 blue) = (2/11)*(2/11) = 4/121
P(red) = 4/11
B = P(2 red) = (4/11)*(4/11) = 16/121
P(green) = 5/11
C = P(2 green) = (5/11)*(5/11) = 25/121
Add the values of A,B, and C to get the probability of getting two of the same color
A+B+C = 4/121+16/121+25/121 = 45/121
This is approximately equal to 0.3719 which is roughly a 37.19% chance of happening
Side note: we can add A,B, and C because they are mutually exclusive events.
Answer: 875
Explaination: in order to find how many words he can read in 25 minutes we need to find how many words he can read in one minute then multiply that by the number of minutes he read. Like this
420÷ 12=35 35x25=875
Answer:
24
Step-by-step explanation:
15/2.5=6
multiply 4 by 6 and you get 24.
