MLR meaning a miss on the first and RL

(.3)(.4)(.7)

but I'm assuming I hit on the first throw.
Sorry for all these replies. I'm not really good with probability.

titusland

so you had 3 events?

I can understand (.7)(.4)(.4), but how did you come up with the other two?
what is your thought process?
Thanks.

yes, you are indeed correct. Do you know of another way of solving it?

Hi All
Thanks in advance for answering my question.

I'm throwing 3 balls at a target.
I win if I can hit 2 in a row.

I must throw with my right hand first, then my left and finally my right again. (Note: Successive throws are independent events)
I estimate that my right hand throws hit the target 70% of the times, while my left hand hit for 40%.

If I hit the target with my first throw, what is the probability that I will win? (Basically hitting on the next throw)

Thanks to both of you for answering this question!
I got it now!
Now, if I had a jar of virtual cookies I'd give you guys some;
but it is mathematically provable that I do not have such a thing.

Hello; please help me with this question:

There are 50 tickets.
3 of them are winning tickets.
Now, I bought 4 out of the 50 tickets.
I want to know the probabilities of
a) My tickets containing all 3 winning tickets, and
b) I do not win anything.

Thanks in advance.
