Gavin and jim win some money and share it in the ratio 4: 5. gavin get £20. home much did they win in total

£45

Step-by-step explanation:

Gavin's share of £20 is 4 parts

Divide by 4 to find the value of one part of the ratio.

£20 ÷ 4 = £5← value of 1 part, thus

5 parts = 5 × £5 = £25

Thus Jim got £25

Hence total won = £20 + £25 = £45

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
