Answer:
Last one:
The probability of the spinner not landing on A and rolling a prime number is 1/3
Step-by-step explanation:
The probability of the spinner not landing on A: 2/3
Prime outcomes on a dice:
2, 3, 5
The probability of rolling a prime number: 3/6 = 1/2
The probability of the spinner not landing on A and rolling a prime number is:
2/3 × 1/2
1/3
Answer:
0.00000763
Step-by-step explanation:
7 accounts for 1 place
6 - 1 = 5, therefore 5 0s after the decimal point
From the graph ⇒ f(-4) = -8
⇒ f(x) = 2x
Using the probability concept, it is found that since the number of red sweets would be a decimal number, the probability cannot be 
<h3>What is probability?</h3>
Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
In this problem:
- In total, there are 8 + n sweets in the bag.
The probability of red is:

Supposing, we solve for n:

10n = 7n + 56
3n = 56
n = 56 / 3
n = 18.67
Since the number of red sweets would be a decimal number, the probability cannot be 7 / 10
