Question

1. Kevin regularly travels from Manchester to Oxford.

He travels on two different trains.
His first train is from Manchester to Birmingham and his second train is from Birmingham to
Oxford.
On the 1st train, the probability that a seat has a table is 3/5
On the 2nd train, the probability that a seat has a table is
3/10
The 1st train has a total of 400 seats.
(a) Work out an estimate for the number of these 400 seats that have a table.

Answer 1

240 seats with tables

Explanation:

Let's start by making our fraction out of 10 on the first train to make it easier on us, this fraction would be
`(6)/(10)`. Then, to get the number of seats on this train that would have a table, we need to multiply 400 by our fraction, giving us:

`400 * (6)/(10) = 2400/10 = 240`

So, the 1st train should have approximately 240 seats with tables.

Hope this helped!
