A bag contains red pens, blue pens, black pens, green pens and purple pens.

A pen is selected at random from the bag.

The table gives information about the probability of the colour of the pen that is selected.

Colour	red	blue	black	green	purple
Probability	0.25	0.10	3y 0 15.	x	y

Show that x = 0.14

Calculate the value of y

A bag contains red counters, blue counters and yellow counters such that

number of red counters: number of blue counters = 5: 2 number of blue counters: number of yellow counters= 3: 4

The number of yellow counters in the bag is 56

Calculate the total number of counters in the bag.
