The answer is 2 , i know it is correct i got 100%
C. Negative because since the neutral atom stands at 0 and positive ions are 1+ and electrons are negative if it gains the electron ( negative ) it will become negative.
Probability of winning a grand prize is 1/10
Probability of winning a basic prize is 11/20
What is the probability of two independent events?
If A and B are two independent events, then P(A and B) = P(A) * P(B).
If Events A and B are independent, the probability that either Event A or Event B occurs is: P(A or B) = P(A) + P(B) - P(A and B).
Solution:
P(A) = no. of A / total possibility
= 4/10
P(B) = no. of 1's/total possibility
= 3/12
= 1/4
Now,
To win a grand prize you need an "A" and "1" .
∴ P(A and B) = P(A) × P(B)
= 4/10 × 1/4
P(A and B) = 1/10
Now ,
To win a basic prize you need to spin an "A" or a "1"
∴ P(A or B) = P(A) + P(B) - P(A and B)
= 4/10 + 1/4 - 1/10
= 3/10 + 1/4
∴ P(A or B)= 11/20

Answer:
43 15/22 degrees
Step-by-step explanation:
The three angles add to 180 degrees
7x+6 +10x-8 + 5x+3 = 180
Combine like terms
22x +1 = 180
Subtract 1 from each side
22x +1-1 =180-1
22x = 179
Divide each side by 22
22x/22 = 179 /22
x =179/22
The smallest angle is
5x+3
5(179/22) +3
895/22 +3
40 15/22 +3
43 15/22 degrees
