Answer:

two coins tossed simultaneously 1500 times and we get two heads 315 times , one head 825 and no heads 360 times. Find the probability of occurrence of these items

Answer 2

i-P(E)=Getting 2 heads

n(E)=315

n(S)=1500

$\bold{P(E) \implies \: \frac{n(E) }{n(S)} = \cancel \frac{315}{1500} \: \cancel \frac{63}{300} \: \frac{21}{100} }$

ii-P(N)=1 head

n(N)=825

n(S)=1500

$\bold{\implies \: \cancel\frac{825}{1500} \: \cancel\frac{165}{300} \: \cancel\frac{55}{100} \: \frac{11}{20} }$

iii-P(E)=No head

n(F)=360

n(S)=1500

$\bold{ \implies \: \cancel \frac{360}{1500} \: \cancel \frac{72}{300} \: \cancel \frac{24}{100} \: \cancel \frac{12}{50} \: \frac{6}{25} }$
