<u>ANSWER:  </u>

Johnny secured 3.695 CGPA.

<u>SOLUTION: </u>

Given, Johnny first semester GPA is 1.39.

And he got B for every subject in his second semester.

We have to calculate his CGPA

First let us calculate his GPA in second semester.

We know that, in semesters terminology B corresponds to 6 points.

As Johnny got 6 points in every subject, his GPA results to 6 points in second semester.

Now, CGPA =\frac{\text { sum of GPAs in semesters }}{\text { number of semesters }}

=\frac{1.39+6}{2}=\frac{7.39}{2}=3.695

So, CGPA of Johnny is 3.695.

Hence, Johnny secured 3.695 CGPA

An unbalanced die is manufactured so that there is a 20% chance of rolling a “six." The die is rolled 6
SIZIF [17.4K]

Answer:

Probability of rolling at least 4 sixes is 0.01696.

Step-by-step explanation:

We are given that an unbalanced die is manufactured so that there is a 20% chance of rolling a “six." The die is rolled 6  times.

The above situation can be represented through binomial distribution;

P(X = r) = \binom{n}{r} \times p^{r} \times (1-p)^{n-r};x=0,1,2,3,.......

where, n = number trials (samples) taken = 6 trials

            r = number of success = at least 4

           p = probability of success which in our question is probability of

                 rolling a “six", i.e; p = 0.20

<u><em>Let X = Number of sixes on a die</em></u>

So, X ~ Binom(n = 6, p = 0.20)

Now, Probability of rolling at least 4 sixes is given by = P(X \geq 4)

P(X \geq 4) = P(X = 4) + P(X = 5) + P(X = 6)

=  \binom{6}{4} \times 0.20^{4} \times (1-0.20)^{6-4}+\binom{6}{5} \times 0.20^{5} \times (1-0.20)^{6-5}+\binom{6}{6} \times 0.20^{6} \times (1-0.20)^{6-6}

=  15 \times 0.20^{4} \times 0.80^{2}+6 \times 0.20^{5} \times 0.80^{1}+1 \times 0.20^{6} \times 0.80^{0}

=  0.0154 + 0.00154 + 0.000064

=  0.01696

<em />

Therefore, probability of rolling at least 4 sixes is 0.01696.
