Answer 1

Given
Totalnumberoftimes2coinsaretossed=500
Nooftimes2Headscomesup=95
Nooftimes1Tailcomesup=290
NooftimesNoHeadcomesup=115

Probabilityof2Headscomingup=
Totalnumberoftimes2coinsaretossed
Frequencyof2Headscomingup
​

=
500
95
​
=0.19

Probabilityof1Tailcomingup=
Totalnumberoftimes2coinsaretossed
Frequencyof1Tailcomingup
​


=
500
290
​
=0.58

ProbabilityofNoHeadscomingup=
Totalnumberoftimes2coinsaretossed
FrequencyofNoHeadscomingup
​


=
500
115
​
=0.23
