You should recognise that this is a binomial distribution model with H representing the number of times the dart hits the target in the first 10 throws as given by the question.
H~B(10,0.1)
Therefore, to work out P(H≥4), you need to change the format for it to be compatible with the cumulative distribution.
In your calculator, you should select MENU SETUP --> 7: DISTRIBUTION --> (Scroll down) 1: BINOMIAL CD --> 2: VARIABLE.
For part c, a new model has been set up where F represents the number of the throw on which the dart first hit the target.
P(F=5) means the probability of the dart hitting the target on the 5th throw, so missing on the first 4 goes and hitting it on the 5th.
Hope this helps.
