42 divied by 3kg the after you get that answer then multiply that by 4kg
Step-by-step explanation:
(a) 1A 2A 3A 1B 2B 3B (6 possible outcomes
(b) Possible outcomes for A or 1 are 1A 2A 3A and 1B ( 4 outcomes) therefore:
Probabilty = 4/6 = 2/3
When finding the probability of two things happening, you multiply the probability of each individual thing happening. The chances of heads are 1/2 and the chances of not a 3 are 5/6. 1/2*5/6 = 5/12. The probability of that is 5/12
