Answer:

1.) the probability of getting 2head is 21/100

2.) the probability of getting 1 head and no head is 79/100

Step-by-step explanation:

1.) 2 heads

Total no. of 2heads are - 105 times

Total no. of events is - 500

Probability = no. of favourable outcomes / total no. of outcomes

Probability of getting 2heads = 105/500

= 21/100


2.) 1 head and no head

Total no. of 1 head = 275

Total no. of no head = 120

Total no. of favourable outcomes = 275 + 120 = 395

Total no. of events = 500

Probability of getting 1 head and no head = 395/500

= 79/100


HOPE IT HELPS YOU!!
