First simplify the number part, 14/2 = 7/1
then the x part,
y doesn't need to be simplified
then simplify the z part, z^-6 = z^6
put it all together...
Answer:
1) Rolling a 3 is unlikely and rolling a 4 is unlikely too.
2) The probability of niki drawing a green marble is likely and the probability of tom drawing a blue marble is unlikely.
Step-by-step explanation:
1) Since there is only one 3 out of 6 numbers, the probability of that outcome is 1/6, which is low. The same thing goes for throwing a 4.
2) The reason why it is equally likely for niki drawing a green is because there are more green marbles than the other marbles. You could see it as a fraction as well, which is 4/9 Which is very close to one half (4.5). For tom, there are less blue marbles which brings it down to the unlikely spot (fraction = 3/9)
Hopefully this helps, and hopefully it isn't too confusing.
Given that speed of car = x miles per hour
Time of travel = y minutes = y/60 hours
(Because there are 60 minutes in an hour)
We have to calculate distance travelled so we will use formula
Distance = speed * time
Distance = x * y/60
Distance = xy/60
Hence choice d) xy/60 is the final answer.
