Hand history
Pre-flop
Flop
The flop is 5♥ 5♦ 4♥ and the big blind checks to you. You hold 8♠7♠: no pair, and no flush equity at all — the board has no spade, so the suit does nothing. What you have is a gutshot. Only a 6 makes your straight. The book puts a hand like this in its GOOD equity bucket on this board: Table 118 prints 58% hand-vs-range equity for gutshots here, which is at or above the 50% floor for Good and below the 75% floor for Strong (p.596). You are last to act with 37.5bb behind and 5.5bb in the middle.
