The second one is d 78 and 82
We can solve this problem using the binomial distribution. A binomial distribution<span> can be thought of as a success or failure outcome in an experiment or survey that is repeated multiple times.
</span>Probability function of binomial distribution has the following form:

p represents the probability of each choice we want. k is the number of choices we want and n is the total number of choices.
In our case p=0.85, k=5 and n=6.
We can now calculate the answer:

The probability is 39%.
.
The equation for area of a triangle is A= 1/2bh so a=1/2(12cm)(9.6cm)
3 to the power of 3 is 9 or 3x3=9
9/3=3
It would be 1/6...
