Question

consider the experiment of tossing a coin. if the coin shows head, toss it again but if it shows tail, then throw a die. find the conditional probability of the event that 'the die shows a number greater than 4' given that 'there is atleast one tail'

Answer 1

@FibonacciChick666

Answer 2

so how many times are you tossing this coin?

Answer 3

do we know, and does it matter?

Answer 4

Nope, as many times. If outcomes repeat we take them only once. As taken in the sample space.

Answer 5

We basically, take all outcomes possible. Instead of the no. of tossing. Yeah :-)

Answer 6

For eg - HH, HT (the two outcomes possible if heads)

Answer 7

We probably won't go taking HHT or HHHHT kinda.
It all gets wrapped in HT :-)

Answer 8

well, it is asking for the conditional probability

Answer 9

so what does that mean?

Answer 10

Well, conditional probability means, probability of an event with respect to the happneing of another event

Answer 11

Here, the condition is there should be a tail
and the other part is the die no. should be >4

Answer 12

ok so that means, we look at them individually first then combine yes?

Answer 13

Is it a NCERT question @Abhilash11 ?

Answer 14

I found the solved one here.Check it out

Answer 15

Apparently yes

Answer 16

Yeah well, this doesnt really make any sense so, :-/ I thought of an easier explanation?

Answer 17

yep, so we start looking at them independently. so first, what is the probability we get a tails

Answer 18

@Wxlfz could you help me with this?

Answer 19

@Abhilash11 Answer is 2/9
