The grid lines will help you find an exact solution (assuming the two lines actually cross at a grid intersection point). However, the two lines may intersect somewhere off the grid lines which is when an estimation will be the next best thing.
Answer:
Step-by-step explanation:
No. Of quarters n(Q)= 3
No. Of dimes n(D) = 5
No. Of nickels n(N) = 2
Total T = 3+5+2 = 10
Prob(D) = n(D)/T = 5/10 = 1/2
Now there are 9 left since it is not replaced back
Prob(Q) = 3/9 = 1/3
Prob(D and Q) = 1/2 × 1/3 = 1/6
Answer:
11 times 2.8
Step-by-step explanation:
11 times 2 is 22. 11 times .8 is 8.8. 22 plus 8.8 is 30.8
Answer:
The probability of rolling a specific number twice in a row is indeed 1/36
Step-by-step explanation:
because you have a 1/6 chance of getting that number on each of two rolls (1/6 x 1/6)
