Answer:
82.125
≈82.12 ( am not sure if it need to be estimated )
Step-by-step explanation:
1 hr -> 10.95
30m-> 5.475
10.95x7=76.65
76.65+5.475=82.125
≈82.12 ( am not sure if it need to be estimated )
there are 10 numbers you want either a 4 or 7 ( 2 numbers)
so probability is 2/10 which reduces to 1/5
