ANSWER

$P(Q \: and \: R)=0.0608$

It was given that,

P(Q) = 0.32

and

Events Q and R and independent events if and only if

$P(Q \: and \: R)=P(Q) \times P(R)$

We therefore substitute the respective probabilities to obtain,

$P(Q \: and \: R) = 0.32\times0.19$

$P(Q \: and \: R)=0.0608$

125 km

Step-by-step explanation:

We are told the train goes 7.5 kilometres in 6 minutes.

So, distance = 7.5 km and time = 6 minutes.

Now, speed is given by;

Speed = distance/time

Speed = 7.5/6

Speed = 1.25 km/min

Now, to find how far it goes in 100 minutes, we will just plug in speed = 1.25 km/min and time = 100 minutes into the speed equation above.

Thus;

1.25 = distance/100

Distance = 1.25 × 100

Distance = 125 km
