11. Two coins are tossed
simultaneously 200 times. We
obtained two heads : 46 times,
one head : 112 times, two tails : 42
times. What is the probability of
getting zero heads ?
O 29/100
O 23/100
Request edi
DO 21/100​

Answer 1

Answer:

21/100

Step-by-step explanation:

two coins toss means sample space =( HH, HT, TH ,TT)

all time heads occur atleast one time. if tail is occur on both coins means 0 heads...

no. of two tails occur = 42 times

probability oh heads = no. of two tails occur/ total no. of coins tossed

p( 0 heads) = 42/200

= 21/100

21/100 ...................
