In the “find the probability one of the counters is red why did you not use the path of red and red?
@1stClassMaths
@1stClassMaths 8 дней назад
Because that would be two reds, not one.

why are there two pass n fail 10:27 for English n one for maths?
@1stClassMaths
@1stClassMaths Месяц назад
This is because we need to consider all the possible options. The top part of the branch is passing maths but then after this you could pass or fail English. The bottom part is fail maths then you could pass or fail English.
