HHH

TTT

HTH

THT

HHT

TTH

HTT

THH

i) Shweta will lose her entry fee if she throws 3 tails,

  Therefore, the probability that she loses her entry fee = 1/8

ii) Shweta will receive double the entry fee if she throws three heads.

    Therefore, the probability that she gets double the entry fee = 1/8

 

iii) Shweta will get her entry fee back if one or two heads show.

     Therefore, the probability that she gets her entry fee = 6/8

                                                                                        = 3/4

Answer 2

2300,46

Step-by-step explanation:

As your question says

total points needed are =2500

points right now =150

level bonus=5

points needed to achieve goal =2500-(150+50)

(here 50 is added because it is level bonus )

=2500-200

=2300

NO. OF LEVEL NEEDED TO PLAY =2300/50

=46
