Answer:
<em>65%</em>
Step-by-step explanation:
Probability that it rains is 12/90
So, probability that it will NOT RAIN is 90 - 12 = 78 out of 90
Independent probability gets multiplied, so probability that it will not rain in 3 consecutive days would be:
P(Not Rain) * P(Not Rain) * P(Not Rain)
First, probability of not raining is 78/90, so:
P(Not Rain) * P(Not Rain) * P(Not Rain)
= 78/90 * 78/90 * 78/90 = 474552/729000
When divided, this will be 0.6509
To convert it to percentage, we multiply by 100:
0.6509 * 100 = 65.09
<em>Rounded to nearest percentage, that will be 65%</em>
