Tom plants 3 seeds.
Rasek [7]

Answer:

A. 64/125

B. 124/125.

Step-by-step explanation:

A).  As the events ( germinate or not germinate) are independent we multiply the probabilities.

Prob(All seeds germinate) = 4/5*4/5*4/5 =  64/125.

B). Probability of at least one germinating =  1 - probability that none germinate

Probability of  1 seed not germinating = 1 -45 = 1/5.

So Prob(at least one germinating)

= 1 - (1/5 * 1/5 * 1/5)

= 1 - 1/125

= 124/125.

The marine needs 14 boats for the 42 people registered for a boat race. How many boats will they need for 6 people?​
Degger [83]

Answer:

2

Step-by-step explanation:

We can write a proportion to determine

42 people          6 people

---------------- = ----------------

14 boats                x boats

Using cross products

42x = 6*14

42x =84

Divide each side by 42

42x/42 = 84/42

x = 2

They will need 2 boats
