Answer:
Probability = 0.356
Step-by-step explanation:
Probability of flooding = 25/100
= 0.25 lets call it p
So probability of not flooding = 1-0.25= 0.75. Lets call it q
So to find the probability of flooding in 1 out of 6 we use combination.
Probabilty = 6C1p^1q^5
Probabilty= 6 *0.25^1 *0.75^5
tienes que dividirla en 2
4.
[(21 + 6) − 3^2] ÷ 9 ⋅ 2.
First work out the parentheses:
= ( 27 - 3^2) / 9 . 2.
Now the exponential:
= (27 - 9) / 9 . 2
= 18/9 .2
= 2 . 2
= 4.
