The Gambler's Fallacy is the idea that past events can affect future behavior. The fallacy often generates real financial consequences for those who like to take their chances at gambling, which, in turn, reaps financial benefits for gambling businesses like casinos or race tracks.
Being a person who enjoys playing dice games, you want to test the Gambler's Fallacy using a six-sided die. You toss the die 300 times with the following results.
 Roll 123456 Frequency 544950515145
Find the value of the chi-square test statistic for this scenario.

We have to find chi-square test statistic
Chi-square test statistic:
χ2=(Oi-Ei)2Ei
Where,
O is observed frequency
E is expected frequency 
Expected frequency -
E = N*pi
Where , N is sample size.
We know that there is equal chance to get any outcome when dice is rolled.
i.e P(1)= P(2) = P(3) = P(4) = P(5)= P(6) = 1/6
Calculation :
 Roll  Observed frequencies, Oi Expected frequencies, Ei(OiEi)(OiEi)2(OiEi)2Ei154300(1/6)=504160.3224950110.023505000045150110.0255150110.02645505250.5 N=300  sum=0.88
We got , Chi-square test statistic = χ2=0.88
