F(x)=3x^2 - 2x +1
f(-1)=3(-1)^2-2(-1)+1
f(-1)=3( 1 ) +2+1
f(-1)=3+3
f(-1)=6
Correct option is B. A discovery in New Jersey actually contributed to the
early economic development of America and, in 1714, a worker uncovered a green rock containing copper.
Here, the use of conjunction 'and' is incorrect as it creates a kind of distortion which seems as if we are talking about two different things: rather then linking the two parts of the sentence, 'and' further disconnects it.
"When" seems better than "And". It clearly indicates the mentioned time. Thus B is the correct answer.

Answer:
111 / 190
Step-by-step explanation:
Let us first compute the probability of picking 2 of each sweet. Take liquorice as the first example. There are 12 / 20 liquorice now, but after picking 1 there will be 11 / 19 left. Thus the probability of getting two liquorice is demonstrated below;

Apply this same concept to each of the other sweets;

Now add these probabilities together to work out the probability of drawing 2 of the same sweets, and subtract this from 1 to get the probability of not drawing 2 of the same sweets;

The probability that the two sweets will not be the same type of sweet =
111 / 190
