No If it was 4 to 3 then yes but 4 can't be multiplied by anything to equal 9
Answer:
0.095163
Step-by-step explanation:
given that a starter motor used in a space vehicle has a high rate of reliability and was reputed to start on any given occasion with probability .99999
Here we find that for any start, there are exactly two outcomes either success or failure.
Also each start is independent of the other since p = 0.99999 for succss is given constant.
Thus X no of successes is binomial with p = 0.99999 and n =10000
If Y is taken as failure then Y is binomial with p' = 0.00001 and n =10000
Required probability
= the probability of at least one failure in the next 10,000 starts
= 1-P(no failure in 10000 starts)
=
230Ibs because altogether is 250Ibs and. Joe is 20Ibs so you subtract 250 by 20 and you get 230Ibs
I believe it’s option #3. hopefully that helps :)
