Answer:
hiiiiihhhhhhhhhhhhiiiiiijkkjj
Given : Different situation of probability
To Find : Identify the following problem whether Experimental or Theoretical Probability.
Solution:
A box contains 5 red and 4 blue marbles. the probability of picking blue marbles is THEORTICAL
A coin was tossed 5 times and the head appeared three times, the probability of landing on tail is EXPERIMENTAL
the probability of red card in a standard deck of cards is THEORTICAL
the word “MATHEMATICS”, the probability of getting a vowel is THEORTICAL
A die was rolled for ten times and the number 4 appeared twice. the probability getting number 4 is EXPERIMENTAL
Probability :
A branch of Mathematics that deals with the study of likelihood of an event to happen.
Two coins tossed at the same time, the probability of landing on both heads = (1/2)(1/2) = 1/4
A box contains marbles which are 5 green, 8 yellow, 10 red and 2 white.
the probability of picking non-red marble = 15/25 = 3/5
A pair of die was rolled, the probability of getting the sum of 8
= 5/36 ( as sum can be 2+6 ,3 + 5 , 4+ 4 , 5 + 3 , 6 + 2)
