Determine whether the number could be the probability of an event. explain your reasoning.
−
0
.
25

-O.25 is not the probability of an event because it does not lie between the value of 0 and 1.

Explanation:

The probability of an event is the measure of the chance that the event will occur as a result of an experiment. The probability of an event A is the number of ways event A can occur divided by the total number of possible outcomes. If P(A) > P(B) then event A is more likely to occur than event B.

The probability of an event must be a number between '0' and '1' (inclusive). In words: The probability of an impossible event is '0'. In words: The probability of an absolutely certain event is '1'

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
