Answer:

402cm

Step-by-step explanation:

middle rectangle: 10 * 12 = 120cm

top and bottom rectangles: the sides will be connected to the 8cm triangle, making their heights 8cm. 8 * 12 = 96cm

side triangles: (10 * 9) / 2= 45cm

120 + (2 * 45) + (96 * 2) = 402cm

Brian flips a fair coin 3 times. What is the probability of getting 3 heads?
earnstyle [38]

If Brain flips a coin 3 times the probability of getting 3 heads is 0.125.

The given statement is Brian flips a fair coin 3 times.

We need to find the probability of getting 3 heads.

<h3>What is probability?</h3>

Probability refers to possibility. A random event's occurrence is the subject of this field of mathematics. The range of the value is 0 to 1.

The possible outcomes are {HHH, THH, HTH, HHT, TTH, THT, HTT, TTT}.

Total number of outcomes = 8

The number of favourable outcomes =1

So, the probability of getting 3 heads = 1/8 = 0.125

Hence, if Brain flips a coin 3 times the probability of getting 3 heads is 0.125.
