Answer:
1:5 simplifies
Step-by-step explanation:
2 are red 10 are black. so it would be 2/10 or 2:10 (both means the same) however if you simplified it, it will be 1:5
A = event that the ball drawn from urn #1 is white
B = event that the ball drawn from urn #2 is white
P(A) = probability of event A
P(A) = (number of white in urn #1)/(number total in urn #1)
P(A) = 3/(3+6)
P(A) = 3/9
P(A) = 1/3
P(B) = probability of event B
P(B) = (number of white in urn #2)/(number total in urn #2)
P(B) = 3/(3+8)
P(B) = 3/11
Because A and B are independent events, we can multiply the probabilities
P(A and B) = P(A)*P(B)
P(A and B) = (1/3)*(3/11)
P(A and B) = (1*3)/(3*11)
P(A and B) = 1/11
Answer: Choice A) 1/11
Answer:
1 7/20 or 27/20
Step-by-step explanation:
Convert the fraction to where the denominators are both equal then subtract 2/5
The answer would be (D) because we know that Tim works out for 35 minutes a day and that if he keeps this constant pace for 4 days then you would end up with the expression: 4 x (25 + 10). Hope this answers your question!
