Under 2.5 Goals — 68% confidence
Both sides have consistently participated in low-scoring encounters. Guinea-Bissau have failed to score in three of their last four matches, producing scorelines of 1-0, 1-0, and 1-1 alongside a heavy defeat to Burkina Faso. Similarly, two of Tanzania's last three recorded games ended in 1-0 scorelines. The tactical caution typical of opening group fixtures supports a low match total.
No — 64% confidence
At least one team has failed to score in four of Guinea-Bissau's last five matches, including consecutive 1-0 shutouts against Egypt and Ethiopia and a 2-0 win over Djibouti. Tanzania also saw one side fail to score in each of their last three recorded fixtures, losing 1-0 to Liechtenstein and Morocco while keeping a clean sheet against Macau.
These two calls are about different parts of the match (total goals and both teams to score), so neither one determines the other. The figure shown is the lower of the two — a combo can never be more likely than its weaker leg.
