To find the probability of both of these occurring, you will multiply the probability of choosing a blue marble by the probability of choosing a purple marble (with no replacement after the first one).
Probability of choosing a blue marble: 17/120
Probability of choosing a purple marble: 18/119
17/120 x 18/119 = 3/140
You will have a 3/140 chance of both of these occurring.
34 inches. How you work it out would be base x height. This means to work out the height, you divide the total area by the base. 136/4 is 34
Answer:
C
Step-by-step explanation:
Since the question is asking for surface area and the dimensions are multiplied by 10, the surface area is multiplied by 10^2, or 100. (For area it would be 10^3, or 1000)
4 / (x+12)
since 4 is divided by the sum 4 would go first ( as you see above) ^^
4÷(x+12)
