1. Can someone help me and explain if you use probability Trees to work out this question..
There are 11 small jars on the table
3 of the jars contain honey
8 of the jars contain jam
Lebron James takes two of the jars at random
Work out the probability that he takes at least one jar of honey.

(3/11 x 8/10) + (8/11 x 3/10) = 48/110 =24/55

You use a tree diagram, for picking the first jar then picking the second (hence the change in the denominator).

Thank you so much

No worries mate
5. You could use prob. tree diagrams but it would save u time if u didnt in the exam but at the end u would get the same answer!
