Answer:
?
Step-by-step explanation:
Answer:
b= -1
Step-by-step explanation:
1/2(b+2) + 3b = -1
b/2 + 1 + 3b = -1
b/2+3b =-2
b+3b=-4
4b=-4
b=-1
In this case, we will first find out the individual probabilities of the events:
Probability (consonant on first spin) = 1/3
Probability (vowel on second spin) = 2/3
Now,
Using the two probabilities we can find out the required probability.
Probability (consonant and vowel) = 1/3 × 2/3
Probability (consonant and vowel) = 2/9
Therefore,
The best answer choice is:
<span>B: 2/9</span>
90 degrees should be right
