There are 27 chocolates in a box, all identically shaped. There 4 are filled with nuts, 8 with caramel, and 15 are solid chocola
AlekseyPX

Answer:

Therefore the required probability is \frac{30}{351}.

Step-by-step explanation:

Two events are dependents event if the occurrence of one of them has effect on the probability of the other.

If A and B are dependents,

then,

P(AB)=P(A)P(B).

Given that,

There are 27 chocolates in a box.

Number of nuts chocolates = 4

Number of caramel chocolates = 8

Number of solid chocolates= 15.

The probability of that a solid candy is drawn is

=\frac{\textrm{Number of solid chocolate}}{\textrm{Total number of chocolate}}

=\frac{15}{27}.

After selecting a solid chocolate, the number of chocolate is= (27-1)=26.

The probability that a nut candy is drawn is

=\frac{\textrm{Number of nut chocolate}}{\textrm{Total number of chocolate}}

=\frac{4}{26}

=\frac{2}{13}

Therefore the required probability is

=\frac{15}{27}\times\frac{2}{13}

=\frac{30}{351}

nirvana33 [79]

Answer:

the answer is 240

Step-by-step explanation:

If 4% are defective, then out of a batch of 250, the number of defective is

4% x 250 = 4/100 x 250 = 10 defective

So, the number of not defective is 250 - 10 = 240 good!
