Answer:

166cm^2

Step-by-step explanation:

To calculate the area of the composite shape, find the area of rectangle and subtract the area of the triangle from it:

Area of rectangle = 16 x 11 = 176cm^2

Area of triangle = 1/2 x 4 x 5 = 10cm^2.

Since the shape is a rectangle, which the supposed shape of a triangle removed, subtract the area of triangle from that of rectangle:

176-10 = 166cm^2

Hope this helps

Good Luck

Two dice are rolled. What is the probability that the sum of numbers rolled is either 5 or 12?

Maksim231197 [3]

<u>ANSWER: </u>

The probability that sum of numbers rolled is either 5 or 12 is $\frac{5}{36}$

<u>SOLUTION: </u>

Given, Two dice are rolled.

We have to find what is the probability that the sum of numbers rolled is either 5 or 12

We know that, probability of an event = $\frac{\text { favourable outcomes }}{\text { total outcomes }}$

Now, total outcomes for two dices = 6 for 1st dice x 6 for 2nd dice = 6 x 6 = 36.

Now, favourable outcomes = sum is 5 + sum is 12

= 4[(1,4), (2,3), (3, 2), (4, 1)] + 1[(6,6)]

= 5 total favourable outcomes.

Now, probability = 5/36

Hence, the probability that sum is either 5 or 12 is 5/36.
