We roll a fair die repeatedly until we see the number four appear and then we stop. The outcome of the experiment is the number
muminat

Answer:

0

Step-by-step explanation:

given that we roll a fair die repeatedly until we see the number four appear and then we stop.

the number 4 can appear either in I throw, or II throw or .... indefinitely

So X = the no of throws can be from 1 to infinity

This is a discrete distribution countable.

Sample space= {1,2,.....}

b) Prob ( 4 never appears) = Prob (any other number appears in all throws)

= \frac{5}{6} *\frac{5}{6} *\frac{5}{6} *\frac{5}{6} *...\\=(\frac{5}{6} )^n

where n is the number of throws

As n tends to infinity, this becomes 0 because 5/6 is less than 1.

Hence this probability is approximately 0

Or definitely 4 will appear atleast once.

There are 100 people in a sport centre.
sleet_krkn [62]

By definition of complement,

Pr[not P | G and T] = 1 - Pr[P | G and T]

and by definition of conditional probability,

Pr[not P | G and T] = 1 - Pr[P and G and T] / Pr[G and T]

Pr[not P | G and T] = 1 - (16/100) / (33/100)

Pr[not P | G and T] = 1 - 16/33

Pr[not P | G and T] = 17/33
