The probability of one head and one tail is 2/3.
<u>Step-by-step explanation</u>:
- The possibilities for flipping two fair coins are {T,T}, {H,H}, {H,T}, {T,H}
- Given the case that at least one coin lands on a head, So the total possibilities are {H,H}, {H,T}, {T,H} = 3 possibilities
- Required event is 1 head and 1 tail= {H,T}, {T,H} = 2 possibilities
To calculate the probability of one head and one tail,
Probability = required events / Total events
Probability = 2/3

Step-by-step explanation:
Answer:
x² + 6x + 9
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
x(x + 3) + 3(x + 3) ← distribute both parenthesis
= x² + 3x + 3x + 9 ← collect like terms
= x² + 6x + 9
Answer:
Vanilla Percentage = 34%
Therefore the number of people who choose vanilla is :
34% x 200 = 68 people
Formula:
Percentage of Object x Total number = Number of Object
