It's pretty simple. What you should tell is:
The car has lost half of it's speed for first 3 seconds of movement (from 4 mi/h down to 2 mi/h). Then it became moving in 2.5 times faster for next 2 seconds (from 2 mi/h up to 5 mi/h) and after that it was moving at constant speed (5 mi/h).

A blue die and a red die are thrown. B is the event that the blue comes up with a 6. E is the event that both dice come up even.

iVinArrow [24]

Answer:

Size of |E n B| = 2

Size of |B| = 1

Step-by-step explanation:

<em>I'll assume both die are 6 sides</em>

Given

Blue die and Red Die

Required

Sizes of sets

- $|E\ n\ B|$

- $|B|$

The question stated the following;

B = Event that blue die comes up with 6

E = Event that both dice come even

So first; we'll list out the sample space of both events

$B = \{6\}$

$E = \{2,4,6\}$

Calculating the size of |E n B|

$|E n B| = \{2,4,6\}\ n\ \{6\}$

$|E n B| = \{2,4,6\}$

<em>The size = 3 because it contains 3 possible outcomes</em>

Calculating the size of |B|

$B = \{6\}$

<em>The size = 1 because it contains 1 possible outcome</em>
