Answer:
Option B.
Step-by-step explanation:
In the given events lets find out the event that has a probability other than 1/2.
A. Flipping a coin gives result of head or tail, so the probability of the result of tails is 1/2.
B. Choosing a vowel from a bag of tiles that contains one of each letter of the alphabet, so the probability of choosing vowel is 5/26.
C. A cube that has numbered from 1 to 6, there are 3 even numbers and 3 odd numbers, so the probability of rolling even number is 3/6 or 1/2.
D. There is 26 red cards in a standard deck of 52 cards, so the probability of choosing red card is 26/52 or 1/2.
Therefore, events A, C and D gives result of 1/2 and B other than 1/2
So Option B is the correct answer.
Answer:
The second plot.
Step-by-step explanation:
In the picture attached, the scatter plots are shown.
The second plot has minimum residuals and its residuals are randomly distributed. Residual is computed as follows:
residual = measured - predicted
It easy to see that residuals of the first option are greater than the second option.
Line of the second option is better than those from third and fourth options because residuals of the second option are randomly distributed, while in the third option, residuals are mostly negative; and in the fourth option, they are mostly positive.
C is the answer since you are trying to make the ys number (-/+) of the value the other y contains
(3) so you will multiply the first equation by -3 to be able to eliminate y
For one boy it would be 4/5, but since its two boys, then it would be 4/5 for the first boy and 3/5 for the second because before any of the names are drawn, there are 4 boys names in the bag and 5 girls names. For the second boy, the would be 3 boys names and 5 girls names in the bag (assuming that the first name drawn was a boys).
