Answer:
P(first marble will be green and the second will be green as well)= 5/22
Step-by-step explanation:
A goblet contains 2 red marbles, 6 green marbles, and 4 blue marbles.
Total number of marbles= 2+6+4
=12
P(first marble is green)=no. of green marbles/total number of marbles
= 6/12
= 1/2
P(second marble is green and we didn't put the first marble back)
=no. of green marbles left/total marbles left
= 5/11
Hence, P(first marble will be green and the second will be green as well)
=
= 5/22
Answer with explanation:
When a Number cube numbered from 1 to 6 is rolled once,
total possible outcome ={1,2,3,4,5,6}
Probability of each outcome that is ,
→So, each outcome has equal chance when a die is rolled 6 times.But in actual ,that is in experimental probability this seems impossible.
→When you are dealing with theoretical probability,we state that ,yes when a number cube is rolled six times each outcome has equal chance of coming.
→No, my friend is Incorrect,because here he is performing experiment in real life,there are chances that in next five trials ,number 5 only appears on the number cube,but when number of rolling of number cube becomes very high and higher, then probability of occurring of each number becomes same.
