How do I solve probability distributions problems step by step?
Start from the definition: probability distributions refers to models describing how likely each possible value of a variable is. Then identify whether the variable is discrete or continuous, then choose the matching model. Follow that same order every time and most questions on this topic become mechanical rather than intimidating.
How to approach it step by step
Most learners lose marks on probability distributions not because the concept is hard, but because the steps get done out of order. This is exactly where a live 1:1 session helps: LetMeTeach solves one problem visually with you, then hands you a similar one and checks each step as you work, adapting the difficulty to how you answer.
Worked example
Coin tosses follow a binomial distribution; heights follow a normal distribution.
The mistake most learners make
Applying the normal distribution to clearly discrete count data.
