Eva wants to know the probability of tossing “heads” at least three times out of five. She used the random number table to simul
umka21 [38]
To obtain the probability of obtaining heads at least 3 times out of 5 times we recall that in her simulation <span>she assigned odd digits to represent heads and even digits to represent tails. Thus, we count the simulated numbers to see in how many numbers do we have 3 or more odd digits.

Below, the simulated numbers with 3 or more odd digits are bolded.

We have 6 simulated numbers having 3 or more odd digits.
Therefore, </span><span>P("heads" at least 3 out of 5 times) = 6 / 16 = 3 / 8.</span>

Two bicyclists are 200 miles apart when they start racing towards one another. If their speeds are 12 mph and 6 mph respectively
Vladimir79 [104]

Answer:

10 hours.

Step-by-step explanation:

Two bicyclists are 200 miles apart when they start racing towards one another.

Their speeds are 12 mph and 6 mph respectively.

Distance = speed × time

Let the time taken by bicyclists = t

We have to calculate the time when they 20 miles apart this means they have covered the distance of 200 - 20 = 180 miles

t(12mph) + t(6mph) = 180

18t = 180

t = \frac{180}{18}

t = 10 hours

It will take 10 hours to both the bicyclists before they are 20 miles apart.
