Answer:

28 reds are expected over the next 40 journeys

Step-by-step explanation:

Here, we want to get the number of reds in the next 40 journeys

From the question, we have that the relative frequency is 0.7

Thus, for the number of reds, we have to multiply the relative frequency by the number of journeys

We have this as;

40 * 0.7 = 28
