Steve has 7 biscuits in a tin.
There are 4 digestive and 3 chocolate biscuits.
Steve takes two biscuits at random from the tin.
Work out the probability that he chooses two different types of biscuits.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

you would make 33% into a decimal, which is 0.33 cents. add it to the   discounted price (aka $28.38). the answer is $28.71
